Sorry, mine is not a two pack, my mistake....
Yes, I just checked the disc and its R1. It still has a lot of bass but now I'll have to try and get the r2 version for comparison 8)
I know this is off topic from the post but I'll say it anyway:
I have the original two pack DTS Jurrassic Park and I hear plenty of Bass in it. Enough to shake my couch in the T-Rex schene.
The movie sounds good to me on my system. I have heard this topic before and was wondering if it is...
